High-integrity Box Girder construction with Top-Running configuration ensures maximum stability. This compact design minimizes deadweight while providing high structural rigidity, making it suitable for diverse and demanding industrial environments.
Leveraging the Low-Headroom concept to provide 15%-30% more effective lifting height. The streamlined structure reduces the load on workshop pillars, significantly cutting down your initial construction and operational costs.
The lower flange of the main beam serves as the precision-machined track for the electric hoist. This integration simplifies the crane structure, improves trolley traveling efficiency, and ensures smoother hoisting performance.
Standard VFD stepless control (Schneider/ABB) for all motions. Achieve millimeter-level positioning accuracy and zero-swing performance, protecting your fragile loads and high-value equipment during heavy-duty operations.
Built with premium Q355B high-strength steel and automated welding. Complying with FEM/DIN standards, our cranes are engineered for a 20-year operational lifespan even in the most rigorous industrial settings.
Featuring hardened gears and self-lubricating drive units to minimize downtime. Integrated with smart overload limiters and safety sensors, ensuring maximum protection for operators with minimal maintenance requirements.

20 tons Overhead Crane is a heavy-duty lifting device designed to handle loads up to 20 tons, widely used in industries like manufacturing, warehousing, and metallurgy. Zomax FEM/DIN Single Girder Overhead Crane is a prime example, featuring advanced control systems, stepless frequency control, and a three-in-one drive mechanism for smooth, efficient operation and low maintenance. Built to DIN, FEM, and ISO standards, it ensures high performance, safety, and reliability, making it an essential solution for improving productivity and safety in various industrial applications.
The 20 tons overhead crane operates on a three-motion system:
Lifting – A double-speed hoist motor controls the steel wire rope to lift or lower the load vertically.
Cross Travel – The trolley moves horizontally across the girder, enabling lateral movement of the load.
Long Travel – The entire crane moves along the runway rails installed on the building structure, providing forward and backward movement.
These three movements work together to allow precise and flexible three-dimensional handling of heavy materials across large industrial spaces.
High Efficiency: Automates heavy lifting, reducing manual labor and increasing throughput.
Space Optimization: The low headroom hoist and compact box girder design make it ideal for facilities with limited ceiling height.
Customizable Design: Tailored lifting height and span meet diverse operational needs.
Smooth & Precise Control: Stepless frequency control and three-in-one motor system ensure smooth operation and accurate positioning.
Durability & Reliability: Built with robust materials and finishes, suitable for harsh environments.
